I have nouveau installed, and I added it to /etc/mkinitcpio.conf then ran # mkinitcpio -p linux, rebooted, and still got this message. I'm not sure why KMS is not enabled, I thought that would enable it.

I've read that the screen not found message might be a result of me running nomodeset as a boot parameter, but if I don't have nomodeset, my boot fails.

Any help would be greatly appreciated

Edit: Also worth noting that when I try to install the nvidia package, it fails
